I've made a detailed simulation using the continuous powergui. When I run the programme following Error comes: "Derivative input 1 of 'hello/Transfer Fcn' at time 1.2 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)."
I'm using Transfer fcn blocks but only for breaking the simulink algebraic loop. when I remove that block then following error comes: Derivative input 1 of 'hello/powergui/EquivalentModel1/State-Space' at time 1.2 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances). Any help would be much appreciated.

Perhaps the 'filtered derivative' suggestion in this blog entry may help.

why the powergui error occured in Matlab?
